Why am I having problems accessing DjVu files for newspapers and other images?
- Alternate Question(s):
Why am I unable to view historical newspaper collections?
Several GALILEO resources, such as the digitized versions of Georgia newspapers in the Digital Library of Georgia, utilize the DjVu filetype. DjVu files require that the user install a browser plug-in to view the images and documents. Sometimes, users encounter problems accessing DjVu files even though they have downloaded the DjVu browser plug-in. Here are a few troubleshooting tips that may help you if you are encountering problems accessing DjVu files:
Supported Operating Systems:
- Windows 8 (desktop mode only), 7, Vista, and XP
- Unfortunately, OSX is no longer supported. The Cuminas Corporation is no longer developing their free DjVu browser plug-in for OSX.
Note: The DjVu plug-in does not function properly on ChromeBooks, iOS or Android.
- Internet Explorer 8 or later
- Mozilla Firefox 15 or later
- Google Chrome 17 to 44 (see workaround below to enable on versions 42-44)
- Safari 5.1.4 or later
- Uninstall the current DjVu plug-in and download and install the newest version of DjVu
- Close all DjVu documents and browser instances before installing.
- Double click on the installer package to begin the installation
- Review the license agreement and select Yes if you agree with its terms.
- Select Close to complete the installation.
- Open browser, navigate to DjVu file, and enable DjVu plug-in
- Disable pop-up blocking for the site. See GALILEO Computer Configuration Instructions.
Enabling DjVu Plug-in
Web Browser companies are implementing stronger security policies in new versions of their browsers. One of these new security settings now requires the user to confirm they wish to allow new browser plug-ins to run after installing them. This is to prevent unwanted plug-ins from running in your browser. Some of these unwanted brower plug-ins can actually be malware, which can cause harm to your computer. Below are the steps to enable the DjVu browser plug-in on different browsers.
Google Chrome before version 42:
- On the right-side of the address bar, click the icon that looks like a puzzle piece with a red X over it
- Select the option to “Always allow plug-ins on xxxxx.galileo.usg.edu (xxxx is the name of the collection you’re viewing)
- Click “Done”
Google Chrome version 42+:
Starting with Google Chrome version 42 (released April 2015), NPAPI support will be disabled by default in Chrome. The DjVu plug-in uses NPAPI, so starting with this version the plug-in will be automatically disabled. To enable NPAPI support and the DjVu plug-in, please follow these steps:
- Typing in chrome://flags/#enable-npapi in the address bar
- Click the link under “Enable NPAPI” to enable plugins.
- Restart Chrome
Note: With the release of Chrome version 45 (September 2015), Chrome will remove the override and NPAPI support will be permanently removed from Chrome, thus the DjVu plugin will no longer work in Chrome. At this time, you will need to use another browser to view historic newspaper collections which still use the DjVu format. The Digital Library of Georgia is currently in the process of converting all historic newspaper collections to a new format, JPG 2000. The JPG2000 format does not require a plugin.
- Once you navigate to a newspaper collection, a notification bar will pop-up underneath the browser address bar. On the right-side of the notification bar, select “Allow” to allow the DjVu Viewer plugin to run.
- After clicking “Allow,” it will ask if you want to “Allow Now” or “Allow and Remember.” Select “Allow and Remember,” so the browser will always allow the plug-in to run.
- Once you navigate to a newspaper collection, a notification bar will pop-up at the bottom of the page. On the right-side of the notification bar, select “Allow” to allow the DjVu Viewer plugin to run.
- After clicking “Allow,” it will ask if you want to “Allow ” or “Allow for all websites” Select “Allow for all websites,” so the browser will always allow the plug-in to run.
- Note: If you’re still unable to view images, make sure ActiveX controls are set to automatically prompt you to enable. Microsoft has instructions on how to do this.
Safari (for Windows only)
- Safari does not require any additional steps after installation.
If you are still encountering problems, please submit a comment to GALILEO support.
